Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, and in particular relates to a sealing structure of a lead-acid battery. Background Art

[0002] A lead-acid battery is a storage battery that uses lead and lead oxide as electrode materials and sulfuric acid solution as the electrolyte. During the discharge process, the main component of the positive electrode of the lead-acid battery changes from lead dioxide to lead sulfate, and the negative electrode changes from pure lead to lead sulfate. During this process, electrons flow from the negative electrode to the positive electrode through an external circuit, thereby generating current. During charging, this process is reversed, and the external power supply forces the lead sulfate to be reduced back to lead dioxide and pure lead on the electrodes, while the concentration of sulfuric acid in the electrolyte increases.

[0003] The prior art discloses a lead-acid battery sealing structure. For example, the patent with publication number CN208240739U discloses a lead-acid battery sealing and clamping structure, including a battery sealing shell, a handle, a sealing clamping foot, a fixing screw, a reinforcing rib, a supporting foot, a first through hole and a sealing gasket. A battery cover is installed on the upper side of the battery sealing shell, a positive terminal connection hole is provided at one end of the upper side of the battery cover, and a negative terminal connection hole is provided at the other end of the upper side of the battery cover. A sealing clamping foot is installed on the lower side of the battery cover, and the lower end of the sealing clamping foot is configured as a barb shape. A sealing clamping groove is provided on the upper side of the battery sealing shell, and the lower side of the sealing clamping foot is clamped in the sealing clamping groove. A first through hole is provided on the upper part of the battery sealing shell.

[0004] In the above patent, the lower end of the sealing foot is set into a hook shape, which facilitates the sealing engagement of the battery cover on the battery sealing shell. The sealing foot can be fixed by a fixing screw to improve the stability of the engagement. Since the connecting piece used is a hook-shaped sealing foot, this sealing foot is indeed very convenient when connecting the battery cover and the battery sealing shell, but it is more troublesome when the battery cover and the battery sealing shell need to be separated, which reduces work efficiency.

[0024] The following is a clear and complete description of the technical solution of this utility model. Obviously, the embodiments described are part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this utility model.

[0025] Example

[0026] See attached Figure 1-5 A lead-acid battery sealing structure includes a sealed housing 1, a connecting plate 10 fixedly mounted inside the sealed housing 1, a plug 12 fixedly mounted on the top of the connecting plate 10, a sealing cover 2 disposed on the top of the sealed housing 1, a clamping mechanism disposed inside the sealing cover 2 for clamping the plug 12, and a releasing mechanism disposed inside the sealing cover 2 for releasing the plug 12;

[0027] Among them, the clamping mechanism includes an outer shell 19 fixedly installed inside the sealing cover 2, a base plate 18 fixedly installed inside the outer shell 19, an insert 13 fixedly installed inside the base plate 18, a fixed block 21 slidably connected inside the insert 13 for clamping the insert column 12, an adjusting block 22 fixedly installed on the fixed block 21, a telescopic rod 23 fixedly installed on one side of the fixed block 21, a mounting block 25 fixedly installed on the side of the telescopic rod 23 away from the fixed block 21, and a second spring 24 sleeved on the side surface of the telescopic rod 23, and the insert column 12 is movably connected inside the insert 13.

[0028] When the sealing cover 2 of the sealing structure is buckled on the sealing shell 1, the pin 12 on the connecting plate 10 inside the sealing shell 1 can be inserted into the plug 13, and the pin 12 is clamped by the fixing block 21 inside the plug 13, thereby realizing a tight connection between the sealing cover 2 and the sealing shell 1.

[0029] In this embodiment, to enable the fixing block 21 to secure the plug post 12, the fixing block 21 is inserted into the annular groove on the side surface of the plug post 12. One end of the second spring 24 is fixedly connected to one side of the fixing block 21, and the other end of the second spring 24 is fixedly connected to one side of the mounting block 25. The other side of the mounting block 25 is fixedly connected to the interior of the housing 19. When the plug post 12 is inserted into the insert tube 13, it contacts the fixing block 21. As the plug post 12 continues to be inserted, the plug post 12 presses the fixing block 21, causing it to move and causing the second spring 24 to contract. Because the plug post 12 is I-shaped, when the annular groove on the side surface of the plug post 12 moves to the fixing block 21, the force of the second spring 24 causes the fixing block 21 to pop out, thereby locking the plug post 12.

[0030] In this embodiment, to enable the fixed block 21 to release the plug 12, the release mechanism includes a limit block 20 fixedly mounted inside the housing 19, a pressure block 14 slidably mounted inside the limit block 20, a connecting bar 15 fixedly mounted at the bottom of the pressure block 14, a pressure plate 16 slidably mounted on the insert 13, and a first spring 17 sleeved on the side surface of the insert 13. The side surface of the connecting bar 15 slides against the side surface of the adjustment block 22. When the pressure block 14 is pressed, it can drive the connecting bar 15 downward. The connecting bar 15 is trapezoidal, and its hypotenuse is compatible with the adjustment block 22. Therefore, when the connecting bar 15 moves vertically, it can drive the adjustment block 22 to move horizontally, thereby causing the adjustment block 22 to drive the fixed block 21 to retract, allowing the plug 12 to be released.

[0031] To ensure that the pressing block 14 can reset itself after being pressed, the bottom of the connecting bar 15 is fixedly connected to the top of the pressing plate 16. One end of the first spring 17 is fixedly connected to the bottom of the pressing plate 16, and the other end of the first spring 17 is fixedly connected to the top of the bottom plate 18. When the pressing block 14 is pressed downward, the connecting bar 15 and the pressing plate 16 drive the first spring 17 to contract. When the force applied to the pressing block 14 disappears, the rebound force of the first spring 17 can push the connecting bar 15, the pressing plate 16, and the pressing block 14 to reset, avoiding affecting the operation of other parts.

[0032] In this embodiment, in order to improve the airtightness of the sealing structure, as shown in FIG. Figure 1 and Figure 2 As shown, a sealing gasket 11 is fixedly connected to the interior of the sealing cover 2, a positive terminal 4 is fixedly connected to the sealing cover 2, a negative terminal 5 is fixedly connected to the sealing cover 2, and a plurality of evenly distributed partitions 9 are fixedly connected to the interior of the sealed housing 1. The sealing gasket 11 is installed inside the sealing cover 2. When the sealing cover 2 is buckled onto the sealed housing 1, the sealed housing 1 will contact and squeeze the sealing gasket 11, thereby improving the airtightness of the sealing structure.

[0033] In this embodiment, in order to facilitate the separation of the sealing shell 1 and the sealing cover 2, as shown in FIG. Figure 1 、 Figure 2 and Figure 4 As shown, the sealing cover 2 is fixedly connected to a support block 6 on both sides, the top of the sealing cover 2 is fixedly connected to a limit frame 7, the interior of the limit frame 7 is slidably connected to a slide plate 8 that fits the sealing cover 2, and the top of the sealing cover 2 is fixedly connected to a handle 3. The limit frame 7 and the slide plate 8 are arranged on the top of the pressure block 14. Pressing the slide plate 8 can hide the pressure block 14 to avoid accidental contact with the pressure block 14. When the sealing cover 2 needs to be opened, it is necessary to press the slide plate 8 to expose the pressure block 14, then hold the support block 6 with both hands, press the pressure block 14 with the thumb, and use the other four fingers to lift the sealing cover 2 through the support block 6. At this time, the sealing shell 1 is separated from the sealing cover 2.

[0034] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the present invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the present invention and various options and variations.
